Abstract: In the preparation of viscose, the cellulose xanthate and the aqueous alkali soln. are separately frozen and comminuted into free-flowing frozen particles, which are then mixed until a uniform mixture is obtained and then thawed to permit the intermixed material to react and form a homogeneous viscose composition. Homogeneous viscose compositions are obtd. because the materials do not react during mixing stage. Reaction is allowed to take place only after a homogeneous mixture has been obtained, viscose soln. can be produced in one third of the time necessary in the prior art. Films produced have better transparency.

Title: Gaseous reduction of molybdenum oxide - in two stages with individual control of temp. and gas compsn.
IPC: C22B34/34
Filed: 1977-04-28
Abstract: Molybedenum trioxide is continuously reduced to metal by feeding it in pelletised form into a first reaction zone where it is heated to 580-650 degrees C in contact with an inert carrier gas containing 3 to 10 mol.% of hydrogen. The flow rate of gas and pellets is such as to provide a stoichiometric excess of hydrogen ranging from >1:1 to 10:1 mols of hydrogen per mol. of trioxide and to effect complete reduction to the dioxide while the heat of the reaction maintains the temperature in the above range. The pellets are continuously transferred to a second zone maintained above 900 degrees C where they are contacted by an inert carrier gas containing 20 to 80 mol.% hydrogen such that reduction to metal is completed endothermically. Finally, the pellets are transferred to a third zone for cooling under protective atmosphere. Pref. the feed pellets pass vertically down the reaction zones in countercurrent to the gas flow. A process for continuous processing of molybdenum dioxide according to the first stage as above is also claimed. The process provides the advantage of continuous operation and permits effective control of the reduction reactions. The prod. is used particularly as a steel making additive.

Abstract: Sawtooth oscillator comprising: a first capacitor (14), a current source (12) having an output (10) coupled to the first capacitor (14) for supplying a charge current (I) to the first capacitor (14), discharging means (20, 22) for discharging the first capacitor (14) during a discharge period (TDS) in response to a voltage (UC) on the first capacitor (14), a second capacitor (30) coupled to the output (10) of the current source (12), interrupting means (26) for interrupting the supply of the charge current (I) to the first capacitor (14) during an interrupt period (TIS) part of which charge current occurring during the discharge period (TDS), supply means (24, 26, 40, 46, 34) for supplying subsequent to the interrupt period (TIS) the first capacitor (14) with a charge surplus built up by the charge current (I) in the second capacitor (30). The current supply to the first capacitor (14) is temporarily interrupted by the interrupting means (48) at least during part of the discharge period. The second capacitor (30) operates as an auxiliary capacitor in which the charge is stored which would otherwise have been supplied to the first capacitor (14). After the interrupt period the charge stored in the second capacitor (30) is supplied back to the first capacitor (14) by the supply means (50). In this manner there is achieved that substantially no charge current is lost during a total period of time of a charge and discharge cycle. In the total period of time the whole charge current of the current source ends up in the first capacitor, so that tolerances in the discharge period no longer affect the oscillation frequency of the sawtooth oscillator. <IMAGE>

Title: Improvements in or relating to the forming of extrusion dies
IPC: B29C48/30
Filed: 1983-05-23
Abstract: A method of forming an extrusion die comprises forming an extrusion aperture 11 in a die piece 10, forcing a flowable materiat 14 partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture 11. by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location. The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.
